Hillary Clinton's 2017 book tour for her campaign memoir, What Happened, drew to a close Friday.

"Returning home after the final week of the book tour for 2017," Clinton tweeted with a gif of her signing a copy of the book, in which she details her experiences as the 2016 Democratic presidential nominee vying for the White House against then-candidate Donald Trump.

"This was the last copy of What Happened I signed at our final signing in Seattle," she continued on Twitter. "What a terrific journey this has been so far, thank you to all who came out & told me your stories."

What Happened hit bookstore shelves on Sep. 12 and had sold more than 300,000 copies by Sep. 30.

It was ranked the eighth most-read nonfiction book on Amazon for the week of Dec. 10.
